Clinical and diagnostic manifestations of tickborne mixed infection in combination with COVID-19.

The coexistence of various pathogens inside the patient's body is one of the poorly studied and current issues. The aim of the study is to identify the relationship between the indicators of complex laboratory diagnostics and the clinical manifestations of a mixed disease during subsequent infection with the SARS-CoV-2 virus using the example of a case of chronic encephalitis-borreliosis infection. Seven blood serum samples were collected from the patient over the course of a year. For the etiological verification of the causative agents of TBE, Lyme disease and COVID-19, the methods of ELISA and PCR diagnostics were used. The patient was diagnosed with Lyme disease on the basis of the detection of IgG antibodies to Borrelia 5 months after the onset of the disease, since she denied the tick bite. In the clinical picture, there was an articular syndrome and erythema migrans. Later, IgG antibodies to the TBEV were found in the blood. Throughout the study, IgM antibodies to Borrelia were not detected. The exacerbation of Lyme disease could be judged by the clinical manifestations of this disease and by the growth of specific IgG antibodies. A feature of this case was that during an exacerbation of the Lyme disease, an infection with the SARS-CoV-2 virus occurred. Treatment (umifenovir, hydroxychloroquine, azithromycin, ceftriaxone) was prescribed, which improved the condition of the underlying disease, decreased joint pain, decreased IgG levels to borrelia. However, during this period, serological markers of TBEV appear: antigen, IgM antibodies, and the titer of IgG antibodies increases. Most likely, this was facilitated by the switching of the immune system to the SARS-CoV-2 virus, with the simultaneous suppression of borrelia with antibiotics and the appointment of hydroxychloroquine, which has an immunosuppressive effect. Despite the activation of the virus, clinical manifestations of TBE were not observed in the patient, which is most likely associated with infection with a weakly virulent TBEV strain. The further course of tick-borne infections revealed the dominant influence of B. burgdorferi in relation to TBEV. Laboratory studies have shown that suppression of the activity of the borreliosis process by etiotropic treatment subsequently led to the activation of the persistent TBEV.

[Time course of changes in cytokines (IFN-γ, IFN-α, IL-18, TNF-α) in the treatment of moderate influenza A (H1N1) pdm09 (2013-2016) with oseltamivir (Tamiflu) and umifenovir (Arbidol) alone and in combination with Kagocel]. / Dinamika tsitokinov (IFNγ, IFNα, IL-18, TNFα) pri lechenii srednetiazhelogo grippa A (H1N1) pdm09 (2013-2016 gg.) osel'tamivirom (Tamifliu) i umifenovirom (Arbidol) v monoterapii i v sochetanii s Kagotselom.

AIM: To assess correlation of cytokines levels and therapy regimes a relationship of the time course of changes in the cytokines IFN-γ, IFN-α, IL-18, and TNF-α to the treatment option for influenza A (H1N1) pdm09 with umifenovir (Arbidol) 800 mg/day for 5 days (n=50); oseltamivir (Tamiflu) 150 mg/day for 5 days (n=50); umifenovir (Arbidol) 800 mg/day for 5 days in combination with Kagocel 72 mg/day for 2 days.; 36 mg/day for 2 days (n=50); oseltamivir (Tamiflu) (150 mg/day for 5 days) in combination with Kagocel 72 mg/day for 2 days; 36 mg/day for 2 days (n=50). A comparison group consisted of 30 healthy volunteers. MATERIAL AND METHODS: The state of immunologic reactivity was assessed twice: at admission of the patients to an infectious disease clinic (at 1-3 disease days) and in the early convalescent period (at 7-8 disease days): venous blood samples were collected to determine the concentrations of IFN-γ, IFN-α, IL-18, and TNF-α by a solid-phase enzyme immunoassay. RESULTS: All the patients in the acute phase of influenza A showed a statistically significant increase in the levels of IFN-γ, IFN-α, and IL-18 as compared with the control group. The groups receiving monotherapy in the early convalescent period had a decrease in the IFN-γ, IFN-α, and IL-18 concentrations that could be compensated by the combined use of the immunomodulator Kagocel. No statistically significant changes in the levels of TNF-α were found in the patients of all the groups, but the groups receiving monotherapy exhibited its lower concentrations in the convalescence period. CONCLUSION: The combination of etiotropic antiviral drugs with Kagocel enhances the efficiency of antiviral therapy. Monitoring of antiviral cytokines during the treatment of influenza A is a convenient tool to verify the efficiency of antiviral therapy and needs to be more widely introduced into medical practice.

The effects of residual pump blood on patient plasma free haemoglobin levels post cardiac surgery.

At the end of cardiopulmonary bypass, there are invariably several hundred millilitres of residual pump blood in the reservoir, which can either be re-transfused or discarded. The objective of this prospective observational study was to investigate the quality of the residual pump blood, focusing on plasma free haemoglobin (pfHb) and blood cell counts. Fifty-one consecutive patients were included in the study. Forty-nine units of residual pump blood and 58 units of transfused red blood cell (RBC) concentrates were analysed. The mean preoperative pfHb of the patients was 0.057 ± 0.062 g/l, which increased gradually to 0.55 ± 0.36 g/l on arrival in the intensive care unit postoperatively. On the first postoperative day, the mean pfHb had returned to within the normal range. Our data showed that haemoglobin, haematocrit, and erythrocyte counts of residual pump blood were approximately 40% of the values in standardised RBC concentrates. Plasma free haemoglobin was significantly higher in residual pump blood compared to RBC concentrates, and nearly twice as high as the pfHb in patient blood samples taken contemporaneously. Our findings indicate that residual pump blood pfHb levels are markedly higher compared to patients' blood and RBC concentrates, but that its administration does not significantly increase patients' pfHb levels.

Combination of ECMO and cytokine adsorption therapy for severe sepsis with cardiogenic shock and ARDS due to Panton-Valentine leukocidin-positive Staphylococcus aureus pneumonia and H1N1.

Sepsis-induced cardiogenic shock in combination with severe acute respiratory failure represents a life-threatening combination that is often refractory to the conventional methods of treatment. We describe the case of a 33-year-old patient who developed acute cardiovascular collapse and ARDS secondary to superinfection of Panton-Valentine leukocidin-positive Staphylococcus aureus and H1N1 pneumonia who underwent successful combination therapy for severe sepsis-related cardiomyopathy and respiratory failure using extracorporeal membrane oxygenation and cytokine adsorption therapy.

"Hanging donors": are we still skeptical about the lungs?

BACKGROUND: Suicidal hanging may cause compression of the neck blood vessels and the airway leading, to hypoxic brain damage caused by cerebral ischemia and respiratory distress. Hanging engenders global tissue hypoxia, particularly affecting the lungs as the result of pulmonary edema and barotrauma. There is scant evidence about outcomes of transplantation with the use of lungs from "hanging donors." This study evaluates the outcomes of lung transplantations (LTx) that use organs from this group. METHODS: We retrospectively analyzed lung "organ offers" and LTx at our center between January 2007 and November 2013. The outcomes of LTx with lungs from donors with hanging as the cause of death ("hanging group") were compared with those with donors having other causes of death (control group), with the use of an unadjusted model as well as propensity score matching. RESULTS: LTx (n = 302) were performed during this period and were grouped on the basis of the cause of death in donors: the hanging group (n = 8) and the control group (n = 294). No statistically significant difference was found in the donor characteristics except for the incidence of cardiac arrest, which was significantly higher in hanging donors. Preoperative characteristics in recipients in both groups were comparable. Intra-operative and post-LTx variables including PaO2/FiO2 ratios, duration of mechanical ventilation, and intensive care unit and hospital stays were comparable. One-year and 3-year survival rates were also comparable in both groups. Two recipients in the hanging group required extracorporeal life support after LTx and could not survive. CONCLUSIONS: Suicidal hanging is a relatively rare cause of death for potential organ donors. Because it does not appear to negatively affect outcomes after LTx, it should not be considered per se a contraindication for lung donation. A word of caution is necessary until we gather larger experience with lungs from hanging donors.

Utilization of the organ care system as ex-vivo lung perfusion after cold storage transportation.

The Organ Care System (OCS) allows perfusion and ventilation of the donor lungs under physiological conditions. Ongoing trials to compare preservation with OCS Lung with standard cold storage do not include donor lungs with suboptimal gas exchange and donor lungs treated with OCS following cold storage transportation. We present a case of a 48-yr-old man who received such lungs after cold storage transportation treated with ex-vivo lung perfusion utilizing OCS.

Oxy-RVAD: rescue in pulmonary complications after LVAD implantation.

Pulmonary complications after left ventricular assist device (LVAD) implantation seldom occur; however, if present, they may prove catastrophic. An Oxy-RVAD (oxygenator in right VAD circuit) is a lifesaving technique in such cases and allows freedom of introducing and removing an oxygenator into the RVAD circuit without opening the chest and competing with LVAD flow.

Outcomes in patients receiving HeartMate II versus HVAD left ventricular assist device as a bridge to transplantation.

OBJECTIVE: Ventricular assist devices have become a standard treatment for patients with advanced heart failure. We present data comparing results after implantation of HeartMate II (HM II) versus HVAD (HW) left ventricular assist devices (LVADs) for the past 7 years at our institution. METHODS: From July 2006 to August 2012, 121 consecutive patients underwent LVAD implantation: 70 (57.9%) received HM II and 51 (42.1%) HW. Patient demographics, perioperative characteristics, and laboratory parameters as well as postoperative outcome were compared retrospectively. RESULTS: Patients in the HM II group were significantly younger (P < .01), with more deranged liver function (higher bilirubin [P = .02] and alanine aminotransferase [P = .01] levels), and had a significantly higher rate of preoperative infections requiring antibiotic treatment (P = .02) and a higher body core temperature (P < .01). Other demographic and preoperative parameters did not show statistical differences. Most postoperative characteristics were also similar between the two groups. HM II patients had a significantly higher transfusion rate, but there were no differences in incidence of resternotomy (P = .156). Recovery and VAD explantation were more likely in the HM II group (P = .02). Although there was no significant difference in survival (log rank test: P = .986; Breslow test: P = .827), HM II patients were more likely to develop a percutaneous site infection (P = .01). CONCLUSIONS: Both HM II and HW provide similar early postoperative outcome and good long-term survival. The differences observed between the groups may be related to demographic and preoperative factors rather than the type of the device used.

[Dengue fever in the Primorye Territory].

Eighteen cases of dengue fever were imported to the Primorye Territory in 2012-2013. The cases were related to visits to Thailand, Indonesia, and Vietnam. Of the 18 patients, 17 and 1 had classic and hemorrhagic dengue fever, respectively.

[A case of Chikungunya fever in the Primorye Territory].

The authors analyze a case of Chikungunya fever imported to Vladivostok. The disease was severe and resulted in disability in a female patient for more than 6 months. There were difficulties in its differential diagnosis with rheumatic diseases.

Surgical pleth index-guided remifentanil administration reduces remifentanil and propofol consumption and shortens recovery times in outpatient anaesthesia.

BACKGROUND: The surgical pleth index (SPI) is an index based on changes in plethysmographic characteristics that correlate with the balance between the sympathetic and parasympathetic nervous system. It has been proposed as a measure of the balance between nociception and anti-nociception. The goal of this study was to test whether it could be used to titrate remifentanil in day-case anaesthesia. METHODS: A total of 170 outpatients were given total i.v. anaesthesia with propofol and remifentanil. The patients were randomized to have the remifentanil dose either adjusted according to the SPI (SPI group) or to clinical parameters (control group). The propofol dose was adjusted according to entropy in both groups. The consumption of anaesthetic drugs, recovery times, and complications were compared. RESULTS: The mean [standard deviation (SD)] remifentanil and propofol infusion rates in the SPI and control groups were 0.06 (0.04) vs 0.08 (0.05) µg kg(-1) min(-1) and 6.0 (2.1) vs 7.5 (2.2) mg kg(-1) h(-1), respectively (both P<0.05). The mean (SD) times to eye opening were -0.08 (4.4) and 3.5 (4.3) min and to extubation were 1.2 (4.4) and 4.4 (4.5) min in the SPI and control groups, respectively (both P<0.05). There was no difference between the groups with regard to satisfaction with the anaesthetic or intensity of postoperative pain. No patient reported intraoperative awareness. CONCLUSIONS: Adjusting the remifentanil dosage according to the SPI in outpatient anaesthesia reduced the consumption of both remifentanil and propofol and resulted in faster recovery.

An erythropoietin gene polymorphism in the hypoxia-responsive element at position 3434 is possibly associated with hypertension.

BACKGROUND/AIMS: Several polymorphisms of vasoactive hormones have been implicated in hypertension. Erythropoietin (EPO) interacts with vasoactive substances, such as angiotensin II. Previously detected single nucleotide polymorphisms in the hypoxia-responsive element of EPO might be associated with hypertension and hypertensive end organ damages. METHODS: 400 hypertensive patients and 200 age- and gender-matched normotensive controls were genotyped for an EPO polymorphism [cytosine (C)/thymine (T) single nucleotide polymorphism] at position 3434. Patients were grouped according to their genotype into the CC group (CC genotype) and the CT/TT group (CT and TT genotype). BP was measured by ambulatory BP monitoring. RESULTS: The CC genotype was present in 87% of hypertensive patients and in 78.5% of controls (p = 0.007). In addition, patients with the CC genotype had higher BP levels compared with CT/TT genotypes (BPsys 143.7 ± 20.4 vs. 136.1 ± 13.5 mm Hg, p = 0.01, and BPdias 85.8 ± 11.6 vs. 82.4 ± 8.9, p = 0.043) despite a nearly identical number of antihypertensive drugs (2.3 ± 1.5 vs. 2.3 ± 1.6; p = 0.257). 100% of the small number of patients with end-stage renal disease (n = 15) had the CC genotype. CONCLUSION: The CC genotype of the EPO gene at position 3434 is more frequently found in patients with hypertension and is associated with higher BP levels.

[Pandemic influenza in Russia: specific features of clinical course and the absence of early etiotropic therapy as a risk factor of severe forms of the disease].

AIM: To assess efficacy and safety of ingavirin in the treatment of the flu caused by pandemic virus of flu A (H1N1) sw1 in hospitalized patients compared with oseltamivir. MATERIAL AND METHODS: A population-based comparative multicenter trial included 194 patients with verified diagnosis of the flu aged 18-60 years with marked clinical symptoms, body temperature over 38 degrees C and duration of the disease 48 hours maximum. The patients were randomized into 2 groups: group 1 (n=152) received ingavirin (90 mg once a day), group 2 received oseltamivir (n=42) in a dose 150 mg twice a day. Duration of the course was 5 days. RESULTS: Ingavirin and oseltamivir normalized body temperature within treatment hours 24-36 if therapy was initiated in the first disease hours 27.0 +/- 10.0 and 31.9 +/- 10.4. Mean duration of the fever for ingavirin was 35.1 +/- 14.5 hours, for oseltamivir--26.3 +/- 13.0 hours (p < 0.817). The antiviral medicines significantly reduced duration of intoxication (head ache, weakness), catarrhal symptoms (cough, tracheitis, rhinitis), rate of complication vs. patients untreated with antivirus drugs (n=30). CONCLUSION: The results of the treatment show safety and efficacy of ingavirin in uncomplicated flu caused by pandemic virus of flu A (H1N1) sw1 in inpatients. Early etiotropic therapy is a basic treatment policy able to reduce the number of severe complications and lethality.

Ex vivo evaluation of lungs from donation after cardiac death after recent cardiac surgery with cardiopulmonary bypass.

Lack of suitable donor lungs is still a major limitation of lung transplantation. Extended donor acceptance criteria combined with innovative assessment tools can be used to expand the number of suitable organs. We describe a successful transplantation of lungs retrieved from a donor who had undergone aortic root replacement 9 days before donation after cardiac death. The lungs were assessed using ex-vivo lung perfusion.

Pulmonary resection for airway complication after lung transplantation in a patient with cystic fibrosis: a case report.

We report a case of the interdisciplinary management of recurring bronchial stenosis after bilateral sequential single-lung transplantation (BSSLT) in a 35-year-old female with cystic fibrosis. Initial bronchoscopic therapy including balloon dilatation, stenting, and cryotherapy for granulation tissue overgrowth was unsuccessful in maintaining airway patency. In view of the persistent left lower lobe (LLL) atelectasis and fibrosis predisposing to recurrent infections, she was submitted for left lower lobectomy.

[Physicians' knowledge on cancer pain therapy : Comparison of palliative care and prehospital emergency physicians in training]. / Wissen verschiedener Arztgruppen über die Tumorschmerztherapie : Vergleich angehender Palliativ- und Notfallmediziner.

BACKGROUND: Palliative care needs a high level of expertise. In particular, there are some potential difficulties in the treatment of patients with the symptom cancer pain (for example lack of education). In Germany, various physicians are involved in cancer pain treatment but in general palliative care patients are treated by a physician who is educated in palliative medicine. In special circumstances prehospital emergency physicians and other physicians are involved in therapy decisions in palliative care patients as well. The authors surveyed different groups of physicians in Germany about their specific knowledge of cancer pain management. MATERIAL AND METHODS: A self-designed, standardized questionnaire (50 items) was given to palliative physicians in training (PP). The survey asked prospectively for knowledge on the World Health Organization (WHO) step ladder of cancer pain therapy. The results were retrolectively compared with an earlier investigation with the same background (emergency physicians in training EP). RESULTS: There was a 99.5% response rate with a total of 654 respondents (PP 185, EP 469) and 461 (70.5%) of the respondents had knowledge of the WHO step ladder for the treatment of cancer pain [PP 164/185 (88.6%), EP 297/469 (63.3%), PP versus EP p < 0.001)]. The correct numbers of therapeutic levels were known by 361/461 participants [PP 151/164 (92.1%), EP 210/297 (70.7%), p < 0.001].The EPs with a professional experience less than 5 years answered statistically significantly more questions correctly (p = 0.004). Concerning the defined parameters knowledge and professional experience, there was no statistically significant difference in the group of PP. CONCLUSIONS: The results of this study verified that the highest knowledge scores were achieved by PPs and overall, the knowledge scores showed an improvement in comparison to previous investigations. In recent years there seems to have been an improvement in education on pain treatment,for example during medical school. Whether this also leads to an improvement of patient care and the relevance of these data for the clinical practice needs to be investigated in further studies.

Recurrent strokes under anticoagulation therapy: Sticky platelet syndrome combined with a patent foramen ovale.

The sticky platelet syndrome (SPS) is a congenital disorder characterized by platelet hyperaggregability to epinephrine and/or adenosine diphosphate; this predisposes affected individuals to acute myocardial infarction, ischemic optic neuropathy, recurrent venous thromboembolism, and transient ischemic cerebral attacks and strokes. Here, we describe an unusual case with recurrent cerebrovascular accidents due to SPS, in the presence of a patent foramen ovale (PFO). We report an unusual case of a 56-year-old female patient with a PFO, who suffered from recurrent strokes despite long-term medication with clopidogrel for SPS. The patient underwent successful transcatheter closure of the PFO, and, in addition, she has been placed on low-dose acetylsalicylic acid. After 18-month follow-up, she demonstrated an intact atrial septum without any vegetations on the percutaneous device until today. She has had no further thromboembolic events.

[Meeting the needs of the European working time directive in german medical profession]. / Sollarbeitszeit und maximale Arbeitszeit bei angestellten Ärzten.

The legal obligation of the European Working Time Directive with its implementation into a German Working Hours Act requires German hospitals to give up old structures and requires the implementation of new working time models. The failure of the revision of the European Working Time Directive in April 2009 prevented that any changes of status quo might happen in the near future. Fundamental terms of the working law for the medical area have been elucidated and have been implemented into concrete calculation formulas. The planned working time has been clearly determined. Particularly, on-call duties and a signed "OptOut-declaration" have huge effects on the upper limit of the working time that is to be determined. Shift duty leads to the greatest limitations of the upper limit of the working time. The Working Hours Act defines the maximal, available, individual working time budget and thus the working time budget of a hospital and it limits the maximal availability of the service providers of a hospital as well as defining the maximal personnel costs. Transparency in this area lays the foundation for an effective time management and the creation of new working time models in accordance with the European Working Time Directive as well as the Working Hours Act and the "TVÄ" (labour contract for doctors at municipal hospitals). It is possible, with the knowledge of the maximal working time budget and the thereof resulting personnel costs, to calculate the economical revenues better. The reallocation of the working time of doctors enables efficiency enhancement. It is necessary to demand a clear definition of the tasks of doctors with the consequential discharge of tasks that should not/do not belong to the responsibilities of a doctor. This would lead to a more attractive working environment for doctors at hospitals and thus to an improvement of the care of the patients. The implementation of the European Time Directive is not to be seen as unrealizable, as has been generally heard; instead, it enables the urgently necessary structural reform at German hospitals.
